Dynamic LTE signal detection

Systems and methods allow LAA LTE equipment to coexist with other services in the unlicensed band such as WIFI or WLAN services. Systems and methods use LTE reference signals in the unlicensed spectrum that are not continuous and can be interrupted by a WIFI signal or other services in the unlicensed band or use a dynamic LAA ON burst or window to provide the LTE reference signals in some embodiments. The systems and methods can detect the presence of LTE signals using a one or more of a number of techniques.
